I think an argument for either position could be made. At one time I was on a race team and we had several people handling our planes. All a little different but we adopted a standard so all planes were the same and that was.
All switches on the left side. Up or aft for ON.
I saw a well know Jet flyer back in the days of Ducted fans . he was doing low flybys and if you get too low you do a wheels up touch and go and about 9 times out of ten it looks cool and the plane flys away missing a little paint....
Unless you have the switches just in front of the nose gear on the bottom of the plane and aft is OFF it then became a obvious that the plane was flying itself to a very large hole in the ground
